CAR. ROOF.

Application filed January This inventionrelates in general to railwaycar roof constructions and more particularly to improvements in the allsteel rigidtype of car roofs.

Objects of the invention are the provision of an all steel rigid roofwhich may be readily and easily assembled, involves comparativelyfewparts, is easily. and inexpensively manufactured, and afiords aplurality of bracing elements and weather-tight joints without requiringcaps for the joints or other closure members; the provision of aconstruction requiring comparatively few rivets butattaining-strengthand rigidity of the roof; and the provision of a construction'havingsimple, compact closed seams, together with such other objects andadvantages oftheinvention as are found to obtain in the structurehereinafter set forth and claimed.

The upper part of the car body, which is the supportingframework of thecar, consists of side plates, formed as either metallic members 10 orwooden members 1'1, and carlines 12', and metallic end; plates 13, Inthe present'instance, the metallic side plates consist of adependingportion 14 Ind an outwardly extending inclined top. flangeextending longitudinally of the car; The end plates 13are bent at theirupper portion to provide an inwardly projecting flange 16 1 extendingfrom side plate to side plate. The carlines 12, in the present instanceare of inverted channel shape and" conform tot-he pitch of the roof,said carlines consistingv of a top web 17 parallel wit-lithe roof sheetsthat engage over-them, and dependingv side flanges 18. The side flanges18 at each end of thecarlines' are bent laterally at 19' to engage thedepending portion of the metallic side plates anda're rigidly securedthereto as by rivets 20/ The top web of the carline is continuedoutwardly at the end to provide an extension 21 for engaging theinclined top flange of the 'sid'eplate and it is rigidly secured'to thelatter by rivets 22. As shown in Fig. 6 the carline is secured to awooden side plate in much the same manner as above described, exceptthat extension 21 is omitted and the top web is depressed at 23 toreceive the top flange 24of a metallic plate 25 that has a dependingportion 26 fitting between the wooden side plate and the laterallyextending flanges19 of the end adjacent of the carline. This toplflange24 is secured to the top web of the car-line by. rivets 27 and thedepending portion is secured between the wooden side plate and the.flangesl b'y bolts 28. e

Intermediate metallic roof sheets are formed as shown to conform to thepitch of the roof. They extend clear across the car from caves to eavesand their ends terminate in depending eaves flanges 31. The eavesportions of the roof sheets are rigidly secured to the side constructionof the car as by rivets 32 passing through said sheets and the topflange 15 of the metallic side plates 14. The roof sheets are secured tothe side construction shown in Fig. 6 by bolts 28 that pass through thedepending eaves flanges 31 of the roof sheets and the wooden side fascia33 and side sheathing 34: and side plate 11.

One side of the roof sheets 29 is bent upwardly at 35 to provide avertically or upwardly projecting flange 36 that extends from side toside of the car longitudinally of the sheet. The opposite side edge ofthe sheet is bent at 37 to provide a vertically extending flange 38consisting of an upwardly extending wall 39 rebent at 41 to provide adownwardly extending wall 42 spaced from the wall 39; and the wall 4-2terminates in an outwardly or laterally extending flange 43 that lies onthe main body of the next adjacent roof sheet and is parallel therewith.When the roof sheets are assembled, the flange 38 is fitted over theflange 36 of the next adjacent roof sheet and these flanges are rigidlysecured together as by rivets 44: thereby providing a beam elementconstituting a closed compact joint which is very strong and rigid andwater-tight and yet is easily manufactured and assembled.

The main body of each of the roof sheets is provided with a raisedportion 45 that is pressed out of the plane of the main body of thesheet. This portion extends longitudinally of the sheet and fits overthe top web of the underlying carline to which it is rigidly secured byrivets 4:6. This pressed out portion 45 is located between the sideflanges 36 and 38 of each roof sheet. It will be observed from theforegoing that the roof sheet is in metal to metal contact at the eavesof the car at all points and the caves of the car are very effectivelyprotected against the weather.

The running board saddles 47 are substantially Z-shaped in crosssection, each being provided with a web 48, transversely extending topflange 4:9 and bottom flange 51. The bottom flange is inclined from apoint 52 intermediate its extremities thus providing flanges 53conforming to the pitch of the roof which are secured by rivets 54k thatpass through the portion 45 and the top web of the carline therebeneath.The running boards 55 extend longitudinally of the car over the ridgeand are secured to the top flange 49 by bolts 56.

The end roof sheet sections are formed similarly to the intermediateroof sheet sections except that one side edge terminates in adependingflange 5'? that is riveted to the end plate by rivets 58.

The invention as hereinabove set forth is embodied in a particular formof construction but may be variously embodied within the scope of theclaims hereinafter made.

I claim:
